APPLICATION FILED DEC. I9. I9IB- Patented Oct. 14, 1919.

rrrrrr v b uili orent mcy 50 drawin Be it known that I,- Pii am, a cit zen of theUnited States, resid n at Davenport; the countylofseott and tats of lowa haveinvented eertainnemandnser ful Improvements in Hog-'Farrowing Guard- Rails, of which the followingiisia spec ficatiOIl. V ii i:::- This invention relates to guard alls ior h0g5 pens, designed particularly; tos zpliovide means wherebyt crushing of: pigfszzllg fthe mother hog against the walls willbeo'lm -iatediev The primary object ofthe invention is to 1 provide a guard rail of simpleand im roved constructimwhichshailbe strong an ble so as not to be broken or rendered less by the mother hog, and which may be easily and quickly folded against the side wall of the pen in order that the area of the pen may be increased if desired.

A further object is to provide guard rails upon the dividing artitions of the pen of such character an construction that the said partitions may be removed easily and stored or piled compactly one upon the other.

A still further object is to provide guard rails of such character that the same when in operative position may be used to sup.-

port the dividing partitions in proper vertical adjustment.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement Figure 1, is a plan view of a conventional pig pen and illustrating the application of guard rails constructed and arranged in accordance with the invention,

Fig. 2, is an enlarged sectional view taken through one of the guard rails and its supporting base, and

Fig. 3, is a front elevation of a part of one of the rails.

Referring now more particularly to the 4 indicates the side walls of a convent1onal hog pen, and 5 the end wall of the en. The pen in the present instance is of t at type wherein partitions 6 are used to provide compartments to be occupied by hogs or pigs which it is desired to keep w ne dunno-RA L;

' The guard 'railsinref indicated at 7, and comprise stout timbers or beams of suitable material of" any desired thickness and breadth. These beams may-be formed of planking, and it isdesiredthat the same when in operative position be'spacedjabout eight inches abovethe' floor'of'the pen,

Z Vz Arranged in spaced relation iupnn the in- 7 nerzwailseaif the- Lng as well siaipon the opposing faces 0 the dividingfwa'lls, are

supporting brackets I theform of; angle plates 8, the samebeing disposed vertically.

These plates are secured in propeg ositiop in any piercrreumanneaafiu eah pres nter its upper end a link 9, the pivots for the links being indicated at 10. It is observed that these pivots are disposed upon the plates near the bases of the same. Each plate or bracket has also pivoted thereto one end of a second link 11, the pivots for the same being indicated at 12. These second links are pivoted to the angle plates below the pivots of the links 9 and near the outer edges of the said plates.

The lower ends of the links are pivotally connected to the upwardly extending portion of an angle plate 13 secured to the upper face of the guard rail 7, and these angle plates are disposed laterally of the said rails. The lower end of link 9 is pivoted as at 14 to the upstanding portion of the plate 13 near the outer end thereof, while the lower end of link 11 is pivoted to the said plate at 15 near the inner end. It is observed that the pivotal connection of the link 11 with the plate 13 is below the plane of pivot 14:. By connecting the links 911 with the plates 813 in the manner shown and described, it is obvious that the guard rails 7 may be easily swung upwardly to the position indicated by dotted lines in Fig. 2, and when in such position the pivots 14--15 will assume a position slightly be yond the vertical plane of the pivots 1012. This particular arrangement enables the rails to remain in upright position and the weight of the rails will be equally distributed to the plates 813 through the pivots 10141215.

To assist in retaining the guard rails in raised position, spring catches 16 are provided. These catches are secured at one end to supporting blocks 17 fastened to the walls upward to the rails 7 when lowered or swung tohofizontal position will project into the gen theproper distance abcve thefioorof t e pen; end it will therefore be impossible for-the mother hog in lying down to mesh the pigs, either against the floor or 'the wall; Shoulditbe desired to increase the area otthe pen: the various rails mey be; grasped and swung osition shown in dotted lines in Fig. 2. he end of each catch will snap over the free edge of its respective guard rail and the latter will be securely held in raised position. Thefree edges of the said rails are provided with a protecting strip 18, to prevent the hogs-orlpigs being injured by splinters and to prevent the rails from hecomlng worn or chafed;

With reference to;Fig@1, it is. observed that the adjacent ends of the railscanied side 4 er thelpeii apart a distance such as wi permit of the partition or dividing well being easily removed, and these ends will assist in securing and steedying the partition when the latter is in place.

7 While the above is a description of the preferred'embodiment of the invention, it is ObYiOEsS tha-t'changes in the details may be resorted to without departing from the invention as defined by the claim.

What is claimed is: p

i A guard structure comprising a support, plates attached thereto, reistively short links pivoted to the plates, relatively long links pivoted to the plates at ints above the ivot points of the short llnks and beyon the rear vertical side thereof, other plates pivotally connected with the short and long links and located between them, and a guard rail attached to the last mentioned plates. 7

In testimony whereof I afiix my signature.
